The dataset used for this study is propreitary and was provided by a private company for this data analysis.  
As such, it cannot be shared publicly. 

Researchers interested in replicating the results of this study should contact Nicola Lacetera as the corresponding 
author.  Dr. Lacetera will make arrangements for access to the dataset on a non-networked computer at his location 
or the location of Dr. Sydnor. Data access will be granted only for the purposes of replication and verification of
the results of this study.  

There are two statistical-program files needed to replicate the results reported in the text.  These files are 
provided in STATA .do file format in the online materials.  Information that would identify the auction company
has been redacted from these programming files, but will be made available to any researcher arranging for access
to replicate the results.  

The primary statistical-program file of interest is the file "RESTAT MS15560-full_analysis_onlineposted.do"  This file
contains the code used to generate all tables in the paper as well as Figures 6 and 7, which rely on estimation results.   
A second statistical-program file is called "RESTAT MS15560-bstrap_onlineposted.do" and is used to  replicate the quantile
regressions from Figure 5.
